WASHINGTON -- President Donald Trump's personal lawyer, John Dowd, confirmed to CNN on Sunday that he wrote a tweet for the @realDonaldTrump Twitter account about the firing of former White House national security adviser Michael Flynn.

"I had to fire General Flynn because he lied to the Vice President and the FBI," the Saturday tweet reads. "He has pled guilty to those lies. It is a shame because his actions during the transition were lawful. There was nothing to hide!"

Flynn pleaded guilty Friday to lying to the FBI about conversations he had with Russia's ambassador to the US during the transition and disclosed that he is cooperating with the special counsel Robert Mueller's office.

"...just couldn't resist commenting on Flynn," Walter Shaub, the former director of the United States Office of Government Ethics, tweeted. "Are you ADMITTING you knew Flynn had lied to the FBI when you asked Comey to back off Flynn?"

California Rep. Adam Schiff, the ranking Democrat on the House Intelligence Committee, tweeted, "If that is true, Mr. President, why did you wait so long to fire Flynn? Why did you fail to act until his lies were publicly exposed? And why did you pressure Director Comey to "let this go?"

Comey said in testimony before the Senate Intelligence Committee that Trump pressed him to end the investigation into Flynn. Trump continues to deny this, and on Sunday morning sent a tweet calling it a "Comey lie."
